Description
crush-map.rst claims that the bucket type defaults are as appear in the table, but they're
not defaults; they must be explicitly specified in the file. Also, how to specify them
is not documented.
CRUSH Map Buckets ----------------- CRUSH maps support the notion of 'buckets', which may be thought of as nodes that aggregate other buckets into a hierarchy of physical locations, where OSD devices are the leaves of the hierarchy. The following table lists the default types. +------+----------+-------------------------------------------------------+ | Type | Location | Description | +======+=============+====================================================+ | 0 | OSD | An OSD daemon (e.g., osd.1, osd.2, etc). | +------+-------------+----------------------------------------------------+ | 1 | Host | A host name containing one or more OSDs. | +------+-------------+----------------------------------------------------+ | 2 | Rack | A computer rack. The default is ``unknownrack``. | +------+-------------+----------------------------------------------------+ | 3 | Row | A row in a series of racks. | +------+-------------+----------------------------------------------------+ | 4 | Room | A room containing racks and rows of hosts. | +------+-------------+----------------------------------------------------+ | 5 | Data Center | A physical data center containing rooms. | +------+-------------+----------------------------------------------------+ | 6 | Pool | A data storage pool for storing objects. | +------+-------------+----------------------------------------------------+ .. tip:: You can remove these types and create your own bucket types.
